Lette/rs Patent No. 92,684, dated July 13, 1869.

INLPROVEMENT IN TOBACCC-CUTTING- MACHINES.

*L *F-i--y- The Schedule referred to in these Letters Patent and making part of the same.

To all whom it ana/y concern Be it known that I, MICHAEL WINTER, of the city, county, and State of New York, have invented a-new and useful Improvement` in vlobacco-Cutting Mt-- chimes, of which the following isa full, clear, and exact description, reference beinghad to the accompanying drawing, forming part of this spccilication, and in whichy Figure l represcntsa side'vicw cf atobacco-cutting machine, in part, having-my improvementl applied to it, ilvith one of the side covers ofthe machine removed, all( f Figure 2, a sectional plan of the same.

Similar-letters of reference indicate corresponding parts. l

My improvement has reference to machines for making line-cut tobacco, in which the tobacco is fed and compressed between endless pitched-chain aprons, and delivered through a contracted throat, where it is en t by a revolving knife, arranged to travel across the feed, in close proximity tothe throat.

.In machines of this description there is constant danger, both as regards breakage of the rapidly-revolving knife, andvto the operator in attendance, oy flying fragments consequent upon such breakage, by reason of the knife striking the throat-piece, which is pro-v duced by the springing or shifting of said throat-piece forward, through pressure of the feeding and compress ing-chain or endless travelling platform against it. This 'is caused by the clogging ofthe chain and its drivingpinion with gumlny.mattei-which oozes from the tobacco during the pressure to which it is subjected in its feed. Such collection of gummy matter also materially interferes with the easy running of the machine.

My invention has for its object the' removal of these objectionsand risks or dangers; and

It consists in the arrangement of a roller, under or at back of the throat-piece, and in proximity to the endlesschain at its front end, in a parallel direction to the driving-pinion, so that ou any tendency of the endless chain to clog with gum, or of gummy matter to collect between it and its driving-pinion, said roller serves to-receive the' forward thrust of the chain con-4 sequent thereon, thereby reliev'ingthe throat-piece of strain, as well as causing the gummy matter to be pressed out from between the chain and pinion, which prevents accumulation of such matter on the chain.

Referring to theaccompanying drawingi l A A represent the two cheeks or side covers of the machine, between which vare arranged the usual upper and lower endlesschain platforms, arranged to lie at a v considerable distance apart in the rear, but approach? ing each other toward the front or throat-end of the machine', so as to compress into a solid form the to bacco, as they feed it to the throat, where the rapidlyrevolving-knife works-in a crosswise direction to effect thccut.V v

down in front, and being extended in the rear, as usual,

so as to lie over the forward end of the chain and form.

said chain and its driver E, and which furtheu'norel serves, by its keeping the chain in close but free gear with its driver, to squeeze out and prevent the accu-V v mulation of such mattei' on the chain, thus easing the v run of the chain and its driver, and relieving the-throat# piece F of all strain upon it or tendency to displaee-` ment by forward thrust of the chain, whereby all dan ger of the revolving knife catching' or striking 'the throat-piece is avoided. Said roller G being free to rotate, in no way adds to thesiiiction of the machine.

Vhat is here claimed, and `desired to be secured by.-
